Question

Calculate the domain of a polynomial function.

a) (-[infinity], [infinity])
b) (-[infinity], 0) ∪ (0, [infinity])
c) (0, [infinity])
d) (-[infinity], 0)

Answer 1

The domain of a polynomial function is the set of all real numbers for which the function is defined. In this case, the domain is the set of all real numbers, which is represented by option a) (-∞, ∞).

Step-by-step explanation:

The domain of a polynomial function is the set of all real numbers for which the function is defined. In other words, it is the set of values that the input variable can take. To determine the domain of a polynomial function, we need to consider any restrictions or limitations on the input variable.

In this case, the polynomial function has no restrictions or limitations on the input variable. Therefore, the domain is the set of all real numbers, which is represented by option a) (-∞, ∞).

Therefore, the correct answer is option a) (-∞, ∞).
